I agree with the other posters here.

I will add this. I think perhaps it is time to admit that you actually are quite angry about several conditions in your life. You have shared them here. The change in meds may be allowing your feelings that have been repressed for quite some time to flow forward in a way that is uncomfortable.

Now is not the time, but I encourage you to connect with these feelings of anger when you are in a better place and work to process them. That might include talking with the people you're angry at and being brutally honest about how you've been feeling. Feelings don't always come forward in the moments where the situations that cause them occur. I experienced this kind of rage when I was sick. It always comes from somewhere.

I am sorry this is happening. I hope you can find some relief soon.
